Abstract:
Objective To evaluate body surface localization by virtue of lnnova CT reconstruction combined with DSA guidance in performing percutaneous fine needle biopsy of lung lesions. Methods Twenty-one patients with solid lung lesions were enrolled in this study. Before percutaneous lung needle biopsy, DSA rotation scanning was performed. Based on the reconstructed lnnova CT images, precise puncture scheme was formulated. Then, under DSA guidance, pereutaneous fine needle biopsy of lung lesions was carried out. Results A total of 41 percutaneous fine needle biopsies was made, of which definite pathologic diagnosis was obtained in 40, with a positive rate of 97.6%. Pneumothorax occurred in one patient (4.8%). Conclusion Percutaneous lung needle biopsy with the help of body surface localization, which is determined by Innova CT reconstruction images, and DSA guidance is a safe and technically-simple procedure with high accuracy in localization. It is of great value in the diagnosis of pulmonary space-occupying lesions.
